Hi all,
I have a 2013 VW Passat TDI and I am looking to replace the fuel filter. Does anyone know if I have to do anything special to prime the filter after installation?
All I had to do with my old vw diesels is fill up the filter with ATF or fuel. I'm not sure what to do with these new fangled machines.
Thanks

Re: TDI Fuel Filter Replacement
Don't use ATF anymore.
High pressure fuel pump may not be able to handle the more viscous oil & the injectors most likely are not designed to handle anything thicker than Diesel fuel.
The owners manual should describe a procedure. I always fill my filters with clean, filtered fuel, but a Cummins engineer instructed me never to do that because there is always the chance a foreign particle bypassing the filtration system & becoming lodged directly into the high pressure fuel pump or injector causing FOD ( Foreign Object Damage ).
I still fill the filters with clean fuel due to the difficulty of priming dry primary & secondary filters using the vehicle's starter & lift pump.
Your car. You decide.
